Abstract
The invention discloses a wear-resistant and corrosion-resistant aluminum bronze brazing alloy. The brazing alloy provided by the invention is composed of the following components in percentage by mass: 10-11.5% of Al, 2.0-5.0% of Fe, 0.4-0.7% of Mn, 0.004-0.015% of Se, 0.02-0.5% of Ti and the balance of Cu. The aluminum bronze brazing alloy provided by the invention is high in strength and hardness and good in wear resistance and corrosion resistance.
Description
technical field [0001] The invention relates to the field of brazing materials, more specifically, to a wear-resistant and corrosion-resistant aluminum bronze brazing alloy. Background technique [0002] At present, the aluminum bronze brazing alloys used for argon arc welding of copper alloys and surfacing welding of steel include domestic existing HSCuAl-B, American ERCuAl-A3, etc., and their standard components are: Al 11.0-11.5%, Fe 2.0-4.5%, Cu balance. The aluminum bronze brazing alloy with this composition has low mechanical properties and poor wear resistance, and, because the β phase is very prone to eutectoid transformation, the formation of (α+γ 2 ), γ 2 The phase is very brittle, and "de-Al" corrosion occurs in the corrosive medium. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a wear-resistant and corrosion-resistant aluminum bronze brazing alloy. ...
